But at length the geologists began to apprehend, what experience soon confirmed, that, extraordinary as were the amounts of gold found in drifts of gravel, and deposits that had been left in the beds of streams, these were merely the signs of far greater riches--merely indexes of the presence of rocks and hills, and underlayers of plains, impregnated with gold, in quantities that the processes of nature could never disclose, and that would reward only the scientific efforts of miners having all the mechanical appliances which the laborious experiments of other nations had invented. The fact of the existence of veins of gold in vast quartz formations, and ribs of gold in hills, was as startling almost as the first news of the presence of the precious metal in the country. This at once changed the prospect, and from a game of chance, elevated the pursuit of gold in California to a grand industrial purpose, requiring an energy and sagacity that invest it with the highest dignity, and to such energy and sagacity promising, with absolute certainty, rewards that make it worthy of the greatest ambition. Now, men of character and capital--the class of men whose speculating spirit is held in subjection by the most exact reason--began to turn to the subject their investigations, and to connect with it their plans. This will account for the fact that has so much astonished the world, which had supposed our Pacific colony to be composed of the reckless, profligate and desperate only--the fact, that when California made her constitution of government, it shot at once in unquestionable wisdom directly and far in advance of all the states on the Atlantic, presenting to mankind the very highest type of a free government that had ever been conceived. The demonstration that California was a _mine_, like other mines in all but its surpassing richness, elevated it from a scene of gambling to one for the orderly pursuit of riches, and by the splendor of its promises, drew to it the most sagacious and most heroical intelligences of the time.
